How can save my link, And hidden this message.
My Controller :-
function orders()
{
$data['orders'] = $this->admin_model->getOrderList();
$data['total'] = $this->admin_model->getOrderCount();
$this->load->view('admin/orders',$data);
}
My Model:-
function getOrderList()
{
$page = $this->uri->segment(3);
if($page=='')
$page=1;
$start = ($page-1)*RECORDS_PER_PAGE;
$end = RECORDS_PER_PAGE;
$this->db->select("*");
$this->db->limit($end,$start);
$this->db->order_by('order_id','DESC');
$result = $this->db->get('wg_orders');
if($result->num_rows()>0)
return $result->result();
else
return 'empty';
}
You can use count()
function as well.
In Controller
function orders()
{
$data['orders'] = $this->admin_model->getOrderList();
$data['total'] = $this->admin_model->getOrderCount();
$this->load->view('admin/orders',$data);
}
In Model
function getOrderList()
{
$page = $this->uri->segment(3);
if($page=='')
$page=1;
$start = ($page-1)*RECORDS_PER_PAGE;
$end = RECORDS_PER_PAGE;
$query = $this->db->query("SELECT * FROM table_name WHERE (your_argument) LIMIT $end, $start ORDER BY order_id DESC ");
$result = $query->result_array();
$count = count($result);
if($count>0)
{
return $result;
}
else
{
return 'empty';
}
}
